Another suggestion for people to try.

Hi Romero

Regarding the toroid - are any of the windings on top of each other or are they all placed next to one another as I move around the toroid?

Thanks
Don

All windings are next to another.

that is not a self runner, its impossible to have it working considering how AC works and the link between the two axes is done via a rubber band. the two motors should be in sync and that will not work using a rubber... must be a chain connection or gears. there are multiple cuts in the video.

I agree with you on this, Romero. There must be some trickery involved. The rotors in those motors do not even have magnets to make any induction possible as a generator, am I right?

Yes everyone is right that it is impossible for it to work but how is he doing it then.
I did figure out 1 way to do what he's doing but with a large amount of modifications to 1 of the motors, cutting away the laminations inside the coil and replace with battery and circuit, you would also have to drill holes into the rotor and install magnets.

I would debunk this but it's just too much work and I won't waste my time on it unless someone else replicates it which I'm sure won't happen any time soon.

those rotors are made of aluminium with iron bits to work on induction. No magnets on them. There are 2 shorted coils on each stator.

no cutting or battery inside, just external power and video editing.

Hi Romero

I finally got back to this device.
It's all wired up but it won't oscillate. 
No Freq showing up on the transformers or any place in the circuit.
I get voltage readings on the different legs of the transistors.
What causes the osc?  the 50pF cap between the transistors?
What is a good starting point for the 80k+47k POT resistors?
Any help would be appreciated.

@dllabarre
50pf is very important but not critical, any capacitor from 30-100pf will work.
Try a toroid recovered from PC PSU, yellow... 2-3 turns on primary.
Check the basic schematic below without the 47k resistor and at the output connect scope terminals or led.
Are the transistors ok? Must work. Once its started then you will need to play with the output (wire turns, capacitor values) , to match the required power needed by the system to keep the battery charged. More voltage going back to the battery will affect the resonance. make sure the frequency remains about the same with or without load or loop back.

Thanks for the suggestions.

I used little orange toroids from a backup power supply.  I'll try to get some yellow ones from a PC PSU.
I bought 10 each of the same transistors in the schematic. I changed them in case one set was damaged.
I'll change back to match the simple schematic you posted.

I've never seen that type of coil, seems to be encased in ferite or something.
